Devices and systems for characterizing a condition of spinal deformities are contemplated. Mobile devices that incorporate inclinometers or accelerometers (e.g., a smart phone) are held securely in a supporting structure that renders it useful to characterize spinal deformities such as scoliosis and/or kyphosis. Supporting structures can include features that secure the mobile device (for example, chamfered surfaces, high friction surfaces, pliant projections, straps, hook and loop enclosures, tensioning devices, detents, etc.) in an upper portion and a lower portion that includes at least one, but preferably two or more rollers, and an interposing centrally placed notch dimensioned to permit the assembled device (supporting structure and mobile device) to span the width of a typical human spinal column. At least one roller includes an encoder (e.g., optical, mechanical, and/or magnetic encoders) that provide data related to their rotation or translation, thereby providing a measure of distance travelled as the device rolls, as well as direction. Such a support device can include additional features, such as additional sensors that are accessible by the mobile device, a centrally placed guide (such as a projected LED laser, illuminated filament, flexible bristle, etc.) that can be used to keep the assembled device in alignment during use, and supplementary battery power for the mobile device.

A foot stretching/checkup device includes: a motor unit; a footrest unit including a lower footrest configured to be rotated about a first rotation axis, an upper footrest configured to be rotated about a second rotation axis and a connecting member connecting the upper footrest and the lower footrest; and a coupling unit including an arm portion rotated by the motor unit and a rotary coupler coupled to the upper footrest. The upper footrest is configured to be rotated by a predetermined angle about the second rotation axis by the rotation of the arm portion. The lower footrest is configured not to be rotated about the first rotation axis by rotation of the arm portion until the upper footrest is rotated by the predetermined angle.

Disclosed are methods and systems to provided planning tools for surgery, particularly for THA. Images of musculoskeletal structure of a patient (e.g. associated with respective planes and in a same or different functional position) may be displayed together and via co-registration and spatial transformations, 3D implants or other objects may be rendered and overlaid in a same position correctly with respect to each image. Measures may be represented with respect to various planes associated with the respective image and/or with respect to an existing implant. A safe zone (graphical element) may be rendered and overlaid with respect to each displayed image to indicate a clinically accepted safe range of positions for the 3D implant. Different instances of implants having respective characteristics affecting range of motion may be available for use during a procedure. For a set of available implants minimal and maximal safe zones may be presented for planning assistance.

A multibend sensor is able to provide information regarding bending of the sensor data in a manner able to mitigate error propagation. A reference strip and a sliding strip are separated from each other by a spacer. Electrodes are located on the reference strip and the sliding strip. The bending of the multibend sensor will be reflected in the shifting of the sliding strip with respect to the reference strip and the measurements obtained from the electrodes.

Provided herein are methods of performing knee surgery, which include comparing a lateral distal femoral angle (LDFA) of the knee with a medial proximal tibial angle (MPTA) of the knee and determining a pre-disease alignment of the knee therefrom. Additionally, prognostic and diagnostic methods for use in knee surgery as well as methods of determining an angle of resection for a distal femur and/or a proximal tibia during knee surgery are provided herein. Also provided is an apparatus for assisting a surgeon in performing surgery on a knee of a patient, the apparatus comprising a processor configured for performing the aforementioned methods. A computer-readable medium having stored thereon a computer program, which, when executed by a computer, causes the computer to perform the aforementioned methods is also provided.

Systems and methods for positioning one or more sensors on a user. The system has user sensors, apparatus sensors, and treatment sensors. A processing device, executing computer readable instructions stored in a memory, cause the processing device to: generate an enhanced environment representative of an environment; receive apparatus data representative of a location of the apparatus in the environment; generate an apparatus avatar in the enhanced environment; receive user data representative of a location of the user in the environment; generate a user avatar in the enhanced environment; receive treatment data representative of one or more locations of the treatment sensors in the environment; generate, treatment sensor avatars in the enhanced environment; calculate a treatment location for each treatment sensor, wherein the treatment location is associated with an anatomical structure of a user; and generate instruction data representing an instruction for positioning the treatment sensors at the treatment location.

A computer-implemented system for processing medical claims is disclosed. The system includes a medical device configured to be manipulated by a user while the user performs a treatment plan; a patient interface associated with the medical device, the patient interface comprising an output configured to present telemedicine information associated with a telemedicine session; and a processor. During the telemedicine session, the processor is configured to receive information from a medical device. Using the device-generated information, the processor is further configured to determine device-based medical coding information. The processor is further configured to transmit the device-based medical coding information to a claim adjudication server.

A system for predicting a three-dimensional human body joint angle according to an embodiment predicts information on a human body joint angle of a new subject by photographing a motion of a subject at different three-dimensional positions and using information on the human body joint angle according to the generated motion of the subject and information on the human body joint angle according to the motion of the subject.

A method includes collecting reference motion data in a device from a motion sensor worn by a user for a movement having a predetermined classification. The motion sensor is attached to a limb having a joint. A user library entry is generated in the device based on the reference motion data and the predetermined classification. Additional motion data is collected in the device from the motion sensor. User motions in the additional motion data corresponding to the user library entry are classified in the device. Range of motion data associated with the user motions is generated in the device. A report is generated in the device including the user motions and the associated range of motion data.

The present disclosure describes transmission systems for use in artificial joints of assistive devices, such as assistive prostheses, orthoses, and powered exoskeletons. A variable transmission is configured to automatically or manually adapt the torque profile to the demand of different locomotion tasks, such as a relatively high torque and low speed profile for a task such as standing up or ascending stairs, or a relatively low torque and high speed profile for a task such as walking.
